Phil Spencer announces Call of Duty deal with PlayStation
"We are pleased to announce that Microsoft and @PlayStation have signed a binding agreement to keep Call of Duty on PlayStation following the acquisition of Activision Blizzard. We look forward to a future where players globally have more choice to play their favorite games."
I am willing to bet that Microsoft knows damn well how rabid the hardcore COD fans are that they wouldn't stop producing the game for a certain console, even just to sell more consoles if their own. It wouldn't be worth it.
I can't say I agree. It's more likely they see the money they'd be leaving on the table and it helps that this makes them look more amiable for future acquisitions.
